HTH, I see where you are coming from but back when classic guitar tones were recorded they were recorded through classic handwired guitar amps with Mullard Valves (or substitute for your favorite NOS), at volumes where they came alive, not a dull sounding Laney VC30 on 3 or a VOX DA5 that needs the tone control on full to get some bite.
A no load pot might just be a cheap route to more twang for some of us players who can't afford amps of the quality that they used to be.
Also, back when the classic guitar tones were recorded, many of 'em used treble boosters, you could conversely say that a good cable and a buffered singnal would be a more natural way to add/retain some sparkle?
They might not of cared about low capacitance cables or buffers but they still wanted the treble man 8)
I'm all for any cheap mod that gives me a tonal option, especially for the price of a pot or cable......
That said, feck it, my Blackguards sound fine as they are :D
